when ever a transmission line orequipments is to be
protected by using distance realy or by differential realy
or merz price protection. A wire is connected between the
CT which is located in different ends of the protection
zone.
This wire provide the path for the circulating current
produce in abnormal condition, which is sensed by the realy
and therefore is tripped.

we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
